Question about Aguilar speaker cabs.

I was just comparing the specs of the different Aguilar speaker cabinets and noticed they state that the GS112 and GS212 use 7-ply Phillipine Mahogany and they do not state that in their other cabinets' specs.

Does anyone know if they use a different kind of wood for their other cabinets?
If so, what wood are the other cabs made out of?
Also, why would they only use the 7-ply Phillipine Mahogany on their 12" cabinets and not the others?

I have e-mailed them with these questions and will give their answers when I get them, but I wanted to know if anyone here knew anything about this.
